SpringBoot项目配置SpringDataRedis

ops/2024/10/21 13:40:26/

1 在SpringBoot中常规的配置

        <dependency><!--自带lettcute客户端--><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId></dependency><dependency><groupId>org.apache.commons</groupId><artifactId>commons-pool2</artifactId></dependency>

RedisProperties类会映射yaml文件中的redis相关配置

    redis:host: 10.20.5.47port: 6379password:database: 0lettuce:pool:# Whether to enable the pool. Enabled automatically if "commons-pool2" is available. With Jedis, pooling is implicitly enabled in sentinel mode and this setting only applies to single node setup. 项目里需要引入commons-pool2依赖enabled: true min-idle: 16max-idle: 16max-active: 64max-wait: 3000

java">// 基于 spring boot starter data redis 3.0@Configuration
@ConditionalOnClass(RedisOperations.class)
@EnableConfigurationProperties(RedisProperties.class)
